Abstract
A connector of an inflating device has a housing having a central chamber and three side chambers. Three connector assemblies are mounted in the side chambers respectively to be coupled with various types of valve stems. Each of the connector assemblies have a valve member and an elastic member, wherein the valve member moves between a close position, in which the valve member isolates the side chamber from the central chamber, and an open position, in which the valve member keeps the side chamber communicated with the central chamber. A rotary member mounted on the housing for rotation to respectively push the valve members of the connector assemblies from the close positions to the open position while the rotary member is turn for the cam portion orientating the side chambers respectively.
